Abstract
MEDICION DE LA VELOCIDAD DE ROTACION (V) DE UN MOTOR MIDIENDO LA (F.E.M.) CALCULADA COMO DIFERENCIA ENTRE EL VOLTAJE DE ALIMENTACION Y LA CAIDA DE VOLTAJE EN LA RESISTENCIA DE LA ARMADURA (RI) O COMO EL VALOR DEL VOLTAJE CUANDO LA CORRIENTE ES CERO. SE PREVE UN ELEMENTO QUE CALCULA LA RESISTENCIA (RI) EN INSTANTES CONSECUTIVOS (T1, T2) Y QUE CALCULA EL VALOR DE LA FUERZA ELECTROMOTRIZ (F.E.M.) DE LA ECUACION F.E.M.=VA-RIXI. EN LOS OTROS CASOS LA (F.E.M.) RESULTA DE MEDIR EL VOLTAJE CUANDO LA CORRIENTE (I) ES CERO MEDIANTE UN MEDIDOR DE CORRIENTE SEGUIDO DE UN MUESTREADOR DE CORRIENTE Y MEMORIA. SE OBTIENE (V) DEL VALOR DE (F.E.M.) POR MEDIO DE LA ECUACION V=F.E.M./K SIENDO K CARACTERISTICA DEL MOTOR.
